Would Riot ever modify voices on old skins that sound weird with default voices??

Would Riot ever modify voices on old skins that sound weird with default voices??

NOT CHANGE LINES LIKE A LEGENDARY SKIN. Just how it sounds - Like with Arclight Varus having his filter removed to sound slightly less demonic.
Skins such as Spooky Gangplank (should sound more spooky) Heartseeker Vayne (I cannot use this silly skin with Vayne's uber serious night hunter voice) and there are several others that come to mind. The skins feel quite odd with their normal voices.
Lines don't have to be changed, just the way they sound - Even a minimal change.
I wouldn't mind an increase in cost for these skins if it made them better...

Thoughts?
Unnecessary or a good idea? Doesn't sound like it'd take too much effort to do, but I haven't a clue :P
